I am still encountering the quest bug for the cloak quest line that forces me to collect 4 pages. It is like nothing changed since the update. However my friend claims that he went from level 1 to 15 on the cloak while only needing to do 1 vision run per cloak level.
I tried deleting the cloak quests from all my characters and then deleting my cache in the WoW folder, but that did not help. Does blizzard at least acknowledge that this issue is lingering around? I have not heard much in the way of a real fix yet.
